avcodec/jpegtables: Unavpriv MJPEG-tables
There are seven MJPEG-tables, five small (1x12, 4x17) and two not small (2x162). These are all avpriv, despite this not being worthwhile due to the overhead of exporting a symbol: The total overhead for each symbol consists of two entries in .dynsym (24B each), one entry in the importing library's .rela.dyn (24B) and one in .got (8B) as well as 2x2B for symbol versions and 4B for symbol hashes in the exporting library; in addition to that, the name of the symbol is included in both exporting and importing libraries, using 2x210 bytes in this case. (The above numbers are for a x64 Elf/Linux/GNU system. Other platforms will give different numbers.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
